The Elantra is one of Hyundai's strongest launches in recent memory, which is saying something considering that the Sonata and the Genesis have been rather well received in mainstream and enthusiast corners.

With that in mind, Hyundai is extending the Elantra line with a sporty coupe variant and a practical five-door hatch for 2013. The cars were revealed on Wednesday at the Chicago auto show.

The Elantra two-door will fight coupes such as the Honda Civic and the Kia Forte Koup and promises 40 mpg on the highway from a fuel-efficient, 1.8-liter four-cylinder. Hyundai is packaging slinky styling and a roomy interior in hopes of capturing young buyers, a common theme for automakers at recent auto shows.

Though it will be hawked as a fun-to-drive option, the front-wheel-drive Elantra coupe will be marketed to a slightly different audience than the more enthusiast-oriented, rear-drive Genesis coupe.

The Elantra coupe will produce as much as 148 hp and 131 lb-ft of torque. It will get up to 29 mpg in the city with the manual and 40 mpg in highway driving. Fuel economy is 28/39 mpg city/highway with the automatic.

The base version checks in at a reasonably lithe 2,687 pounds. The styling continues Hyundai's fluidic sculpture theme with a flowing beltline, prominent headlights and slightly flared wheels.

The coupe continues the momentum started by its sedan sibling, which won North American Car of the Year honors in January.

Hyundai is also adding a five-door model, the GT, that will fight the Ford Focus, the Mazda 3 and the Volkswagen Golf. The five-door offers the same powertrain choices as the coupe and gets 28 mpg in the city and 39 mpg on the highway. The compact hatch is shorter than the coupe.

The Elantra GT also has up to 51 cubic feet of cargo capacity in the rear with the seats folded down. A version of the car, the i30, was revealed for other markets last year in Europe.
